GAGE.

Specification of Letters Patent. l

Patented Feb. 8, 1921.

Application led September 10, 1918.l Serial No. 253,436.

lod/Z ur/10m tmc/y concern lie it known that I, DoLrH Sronir, a citizenthe ited States, residing at Thompson. the counts,rv ot lVinnebago andState have invented a new and useful finge. oi' which the 'following` isspeciti- .L tion. 'i his ini ention relates to a combined nd testinggage primarily dee i aging and correcting connelx in L y one of theobjects of the provide a simple and co' mit st ucture bv nieans ot whichthe rf .in bf. tes-en tor straightness and for twist auf. where? afterany defects of this nature have beenlocated and corrected, the

bearing in the rod can be reanied quickly and accurately to give around, smooth. bearing of perfect lit, thus insuring accurate .i seinblyand operation of the parts without the advantages of the invention asset forth in the appended claims.

ln the accompanying drawings the pre- Jerred form ot' the invention hasbeen i igure l is a perspective View of the gage, a connecting rod beingshown in position therein to be tested for alinement.

2 is a central longitudinal section h the p C twist. vfor testingstraightness, and. tor t' t ning the bearing cap.

3 is a section on line S-f, Fig. 2. ig. 4 is a perspective view ot thereanier to be used with the gage.

Referring to the ligures by characters of reference, l designates a baseplate adapted to be attached to a support in anyv manner ,-55 desiredand having upstanding side flanges wardly as shown at 5 to constitutegage surfaces tor use in gaging alinement. Rests 6 are formed at theother ends of the flanges 2 and are equal in height, these rests beingused in testing 'for twist. The base 1 is cut away between the ribs 2 to'form a slot 7 which extends between the lugs l and inwardly toward thecenter of the base.

When it is desired to test a connecting rod lt for straightness of itslongitudinal axis an arbor S is inserted through the bearings 3 and alsothrough the bearing of the rod R. Said rod is then swung to positionbetween the rests 6 and, ii straight, will enter freely therebetween. Totest for twists, an arbor 9 is inserted through the eye in the end ofthe rod R and caused to bear on the rests 6. Should it only contact withone of the rests it would indicate that the rod is twisted and wouldalso show the amount of correction necessary. Alinernent'ot the rod :1a.

readily sight along the faces while the arbor e is in position. therebyto determine to what extent the rod has been bent, and the amount ofbending necessary to straighten the rod. .es the faces 5 are inclinedthey can be used in gaging rods which vary in length.

The bearing of the rod can be reamed by removing the cap C of thebearing and filing oli1 a small thickness thereor". A. reainer l0 havingcylindrical bearing portions 1l. at the ends thereof and a square headl2 is inserted in the bearings 3 in lieu of the arbor 8, the rod R issuspended between the rests 6 and against the reamer, and the cap isadjusted tightly against the rearner and secured to the rod. By thengiving the reamer a turn with a wrench or the like, the bearing in therod will be quickly and accurately rounded and smoothed. rl`hus, inabout one tenth the time ordinarily required to scrape and lit aconnecting rod,

a rod can be properly reamed and straightened by means of the presentdevice and can be put in place and used without the necessity of againremoving it to make further changes.

What is claimed is 1. A device of the class described including a base,spaced upstanding lugs at one end of the base and having outerdownwardly inclined faces forming an alinemen't gage, spaced rests atthe other end of the base, central bearings at the sides of the basebetween the lugs and rests, and means detachably mounted within thebearings for insertion into the bearing in one end portion of aconnecting rod.

2. A device of the character described including a base, centralbearings at the sides thereof, a member insertible into the bearings andthrough the bearing in one end of a connecting rod, lugs at one end or"the base and spaced apart to receive between them one end portion of theconnecting rod supported between the bearings, said lugs havingoutwardly and downwardl 1 inclined faces, anv arbor insertible throughthe rod for engagement with said faces, and rests at the other end ofthe base and spaced apart to receive the end oi' the rod therebetween',said rests constituting twist gages for engagement by said arbor Whileinserted in the rod.

3. A device of the character described inl cluding a base having,Central side bearings,

a detachable member insertible into the bearings to support between thebearings one end of a connecting rod, lugs at one end or" the base andhaving downwardly and outwardly inclined gage faces, said lugs beingspaced apart to receive one end portion of the rod therebetween, spacedrests at the other end of the base and forming a twist gage, and anarbor insertible -into the other end of said connecting rod and movabletherewith to position upon the lugs and the inclinec "faces of therests.

1l. i device of the character described including a base having centralside bearings, a member having bearing portions mounted in the bearingsand a portion between the bearings, said member constitut ing a supportior one end of a connecting rod, lugs upstanding :from one end el the hae and having outwardly and downwardly inclined gage faces, restsupstanding from the other end oi the base and forming twist gagemembers, an arbor insertible into the other end of said connecting rodand movable against the lugs and rests, there being a slot in the basebetween the lugs i'or the reception o'i the connecting rod.

ln testimony. that i claim the foregoing as my own, I have hereto aiixedmy signature in the presence of two witnesses.
